Description
With detectors at both Fermilab and Ash River, Minnesota, in the United States, NOvA
was built to investigate the intricate properties of neutrinos, with a principal emphasis on active
three-flavour neutrino mixing phenomena. Comprising two functionally identical detectors, with
the Near Detector located 1 km at Fermilab and the Far Detector located 810 km away and 14
mrad off the beam axis in Northern Minnesota, NOvA capitalizes on the expansive distance to
scrutinize neutrino behaviour.
NOvA not only probes active neutrino mixing but also explores exotic oscillations, including
sterile neutrinos. Uncertainties on the neutrino flux, cross-section, and detector systematics
significantly contribute, complicating the disentanglement of genuine physics events from
background noise. This talk presents the impact of systematic reduction via near detector neutral
current samples and its implications on oscillation parameters, leveraging results primarily
from Monte Carlo simulations. We aim to enhance the active-sterile neutrino oscillation by
constraining the systematics.
